流速を一定に制御したものである。In order to clarify the above-mentioned problems, as a result of measuring the vibration and the frequency of the vibration of the steel sheet in the cell, the width of the steel sheet is particularly narrowed, and the amount of pushing in the edge mask is large. At the same time, the vibration of the steel sheet increased, and as a result of frequency analysis, it was found that the cause was due to the flow of the plating solution. Therefore, the present invention, in order to solve the above problems, the width of the steel sheet during the passing,
The software controls the flow rate of the plating solution flowing through the cell by detecting the usage state of the edge mask, and controls the plating solution flow rate in the cell to be constant.

１／３に減少した。FIG. 2 and FIG. 3 show one embodiment of the present invention. The software that changes the relationship between the width of the steel sheet and the flow rate of the plating solution as shown in Fig. 2 was created and used, so the vibration amount of the steel sheet became as shown in Fig. 3, and the spark generation rate was reduced to about 1/3 of the conventional rate. Diminished.
